چکیده

Fibre optic radiation monitors have promising applications in the nuclear industry. We investigate the possible use of PMMA plastic optical fibres as on-line dosimeters, based on the measurement of the attenuation induced by the ionising gamma radiation. A novel interrogation scheme is proposed for real-time dosimetry applications. This technique involves using spectral measurement techniques without regard for the absolute intensity.

Fricke Gel Dose Indicators Applicable for Blood Irradiators

Introduction: Transfusion of irradiated blood is recommended by the guidelines for cardiosurgery, cancer surgery, severe trauma and congenital immune deficient recipients. To prevent post- transfusion graft-versus-host disease (PT-GVHD), blood cells may be irradiated by gamma rays. The absorbed dose range for blood irradiation is typically 15 to 50 Gy. As the assurance that blo...

Polymethylmethacrylate/Silver Nanocomposite Prepared by γ-Ray

Polymethylmethacrylate-silver (PMMA/Ag) nanocomposite is synthesized by irradiating the solution of silver ions in methylmethacrylate monomer by γ-ray. In this method, polymerization of the methylmethacrylate monomer and the silver ion reduction occurred simultaneously. Optical properties of the PMMA/Ag solutions are investigated using UV-Vis spectroscopy. The structural characterizations of th...

An investigation into the potential applicability of gel dosimeters for dosimetry in boron neutron capture therapy

Background: The aim of this work was to establish how well gel dosimeters performed, as substitutes for brain tissue compared with standard phantom materials such as water, polymethyl-methacrylate (or PMMA), A150 plastic and TE- liquid phantom material for dosimetry of neutron beams in boron neutron capture therapy. Materials and Methods: Thermal neutron fluence, photon dose and epithermal neu...

Polymer Optical Fibre for in Situ Monitoring of Gamma Radiation Processes

Poly Methyl MethAcrylate (PMMA) based plastic optical fibres offer a low cost radiation monitoring solution with a wide dose range, capable of providing real-time, online information. The sensitivity of the fibre to ionising radiation is shown to be dependant on wavelength, with the sensitivity increasing with decreasing wavelength, and so by carefully selecting the monitoring wavelength, the d...
